Description

Technical Field

[0001] The utility model relates to the technical field of coal mills, in particular to a coal mill with controllable coal feeding amount. Background Art

[0002] A coal mill is a machine that crushes coal lumps and grinds them into pulverized coal. It is widely used in industries such as electricity, metallurgy, chemicals, and building materials. As key equipment for coal pulverization, coal mills play an important role in multiple industries. Through reasonable model selection, correct operation, and regular maintenance and servicing, efficient and stable operation can be ensured. The coal pulverization process is the process by which coal is broken down and its surface area continuously increases. To increase this new surface area, the binding forces between solid molecules must be overcome, which consumes energy. Coal is ground into pulverized coal in a coal mill primarily through crushing, pulverizing, and grinding. Crushing consumes the least energy. The pulverization process is the most energy-intensive. Various coal mills combine two or all three of these methods in the pulverization process, but the primary method depends on the type of mill.

[0003] The coal mill in the existing technology is generally not convenient for adjusting the amount of coal added, and when the amount of coal is too much, it is easy to cause the coal mill feed port to be blocked, and when the amount of coal is too little, it is easy to reduce the coal grinding efficiency, thereby reducing the practicality of the coal mill. Therefore, we need a coal mill with controllable coal addition amount. Utility Model Content
